YAOUNDE -- At least 19 people were killed and 50 others injured in twin suicide attacks Friday at a market in Cameroon's Far North region bordering Nigeria, security sources have said.

Two young men carrying explosive devices exploded them at the market, killing about 10 people and injuring several others, the sources said.

After the admission into hospital, some of those injured died, bringing the death toll to 19, including the two suicide bombers.

No group has claimed responsibility for the attack, but Cameroon's intelligence services are pointing fingers at Boko Haram, a Nigerian terrorist group operating in Cameroon's Far North region.
